Method and apparatus for producing optical displays
First Claim
1. A method of creating an optical display which comprises:
- producing a representation of a real optical scene;
establishing an image transmission path with the path including a stage at which the representation is produced; and
projecting a parameter of the representation onto the real optical scene, whereby a combined optical display is produced comprising the real optical scene combined with a parameter of the representation of the real scene.

Abstract
Method and apparatus are disclosed for creating optical displays from a real optical scene with an optical feedback circuit projecting a parameter of the original scene for combination with the original scene itself or an image thereof. The feedback circuit may influence the parametric image in many ways to influence the combined optical display. For instance, the parametric image may be a negative of the real scene to produce a null combined display showing motion where the parametric image is time delayed or the parametric image may be defocused to produce a combined display with edge enhancement. The feedback circuit may project a vertical parametric image to create fixed relation combined displays or the feedback circuit can project real parametric images continuously to create a combined display which changes progressively as a function of the relation between original and parametric images. The method and apparatus may be used for a variety of purposes such as motion detection in security devices or live sperm counting or real image enhancement in biological microscopy.
